The number that 250% of is 50 has to be determined.

Let it be X.

X*`(250/100)` = 50

=> X = `5000/250`

=> X = 20

50 is 250% of 20

250% of ? is 50

To solve this equation, use 250/100 = 50/x 

Now multiply 250 with " x " and 100 with 50

By multiplying, you should get

250x =5000 now divide both sides by 250

By dividing, you should get

x = 20 which is your answer for " x "

250% of ? is 50

`250/100=50/x`

`250x=5000`

`x=20`

250% of x is 50

2.5x= 50

you have to get x alone

the way to do this is by dividing by 2.5

this way you get 

20 as your answer

so that would be 2.50 X = 50

divide both sides by 2.5 and you get 20

Wiggin42 | Student

250% of ? is 50

250% in decimal form is 2.5 

Rewrite: 

2.5x = 50

x = 50/2.5

x = 20

250% of ? is 50

set up the problem into a fraction 

`(250)/(100)` is the same as `(50)/x`

`(250)/(100) =(50)/x`

cross multiply 

`250xx x = 250x    `

`100xx50=5000 `

`250x=5000`

divide by 250 to get x by itself

`(250x)/(250) = (5000)/(250)`

x= 20

50 is 250% of 20

najm1947 | Student

Let x be the number whose 250% is 50

then 250% of x = x*250/100 = 5*x/2 and this is equal to 50, given

5*x/2 = 50, multiplying both sides with 2/5, we get: 

x = 50*2/5 = 20

50 is 250% of 20
